摘要：

A CSS technique for depositing large-grained, well-orientated Sb2Se3 thin films has been developed, and solar cells based around this material have been fabricated. Adapting a standard CdTe methodology can produce high efficiency devices in a FTO/TiO2/Sb2Se3/P3HT/Au heterostructure. The influence of temperature during deposition is examined to show larger columnar grain growth at increasing source temperature. Optimising the temperature of deposition both increases the proportion of grains in the correct orientation and balances the improvements due to larger grains while limiting void formation. At optimized conditions of 475 degrees C, the peak performing device exhibited a maximum PCE of 4.3%.
